To all whom it may concern:

Be it known that I, EDWARD B.'BRO }LEY,'

Therefor, of which the following is a specification.

This invention relates to an improved process of packing glass and a preservative composition therefor, and has for lts primary object to provide means for preventing the discoloration of a glass surface caused b the rotting of the straw in whlch it is pac ed for shipment.

It is a more particular ob ect of the 1nvention to provide an improved process for the above purpose involving the a-ppllcation to the surfaces of the glass of a preservative composition consisting of sulfuric acid, oil and water.

And it is another object of the invention to provide a further step in the process which consists in the application of a preservative agent to the straw in which the glass is packed, whereby rotting of the straw is prevented.

ith the above and other objects in view, the present invention consists in the improved process which I have herelnafter set forth and the preservative composition in? volved therein whereby the desired end may be attained.

As is well known to manufacturers of window-pane glass, the surfaces of the glass frequently become discolored by the rotting of the straw in which the glass is packed for shipment. This discoloration is ineradicable so that the glass is worthless for any useful purpose.

The staining or discoloration of the glass surface is caused b the sweating of the glass, due to atmosp eric changes, which in turn rots the straw in which the glass is tightly packed. Fumes are generated by the rotting straw which burn the glass and cause the surfaces thereof to become greatly discolored or stained. This discoloration in many cases is such as to render the glass opaque. It is, therefore, the pr1mary purpose of the present lnventlon to provide a simple and efiective remedy for this dilfi- Speciflcation of Letters Patent.

culty and thereby obviate considerable monetar loss. v

'l o the above end, I first prepare a composition by thoroughly mixmg together one teaspoonful of sulfuric acid, one teaspoonful of crude lubricating oil, and one int of water. This composition is strained t rough cheese-cloth or other suitable material, and is then sprayed upon the surfaces of the glass. It will, of course, be apparent that the composition may be prepared in a larger quantity, adhering substantially to the proportions of the ingredients as above given, so that the glass can be dipped in the solution. It has been demonstrated that such a preservative composition applied to the glass eifectuall prevents the staining or discoloration of t e surfaces by the rotting of the packing straw. The sweating of the glass improves or enhances this attribute of the coatlng preparation. Preferably, however, after the glass has been acked in the straw, the straw is sprayed wit creosote, which has a tendency to prevent the rotting of the straw. The glass thus packed for shipment will not be injuriously affected in any climate to which it may be trans ported. The invention has been severely tested by subjecting the glass after packing to high temperatures, and has emerged from such tests without the slightest discoloration.

From the foregoing description, it is believed that the several features of my process and'preservative composition and the manner in which the invention is to be carried out in practice will be clearly and fully understood. The composition is simple and the several ingredients thereof may be obtained at nominal cost. This composition is easily applied to glasssurfaces and the treatment of the glass and straw in the manner hereinbefore explained will consume but little extra time in the packing of the glass for shipment.

I claim 1. The herein described process of pack ing glass for shipment which consists in first coating the surfaces of the glass with a composition containing sulfuric acid, lubricating oil and water, and then packing the glass in straw.

- 2. The herein described method of packing glass for shipment which consists in a composition containing furic acid and lubricating oil, and then equal parts of sul -i packing the glass in a vegetable cushioning ma- 5 terial.

3. The herein described preservative com-' position for glass consisting of sulfuric acid,

crude lubricating oil, and water.

i. The herein described preserve tive comsignature in t position for glass consisting of sulfuric acid 10 and; lubricating oil in equal quantities, and water. A i
